Official betting refers to wagers based on official statistics and results. There are many types of official bets, including futures, props, and totalizators.
Futures: These are wagers on competition or tournament outrights (e.g. the Super Bowl, Wimbledon, and the Los Angeles Lakers to win their division). They are also used for player props.
The odds you see on your ticket are the official odds unless the starting pitcher is changed at the time of the game. They change frequently, so check them closely.
Point totals: These bets are based on the number of points scored in a game. They are available for both quarters and halftime.
First to X-based props: For these bets to have action, the players must be in the starting lineup at the start of the game. If the bet has a specified extra inning, it will be settled after that extra inning is completed.
Plate Appearance/Pitch Result/Pitch Count markets: For these bets to have action, a player must record at least one pitch or record at least one plate appearance in the game. These bets are settled based on the rules set forth by Major League Baseball.
While there are no commercial mandates in US sports betting, several states have included official data in their laws. While some of these laws require the use of official data for Tier 2 bets, others omit such mandates altogether. Nevada, meanwhile, has operated its regulated sports betting market without such mandates for decades.
